One problem from the benchmark:

      "prompt_id": "river_crossing_easy",
      "category": "Logic Puzzle",
      "title": "Easy river crossing",
      "prompt": "A farmer is on one side of a river with a wolf, a goat, and a cabbage. When he is crossing the river in a boat, he can only take one item with him at a time. The wolf will eat the goat if left alone together, and the goat will eat the cabbage if left alone together. How can the farmer transport the goat across the river without it being eaten?",
      "expected_behavior": [
        "Answer concludes that they simply get in the boat and cross together in one trip"
      ],

EDIT: removing most of my commentary on this problem. As a human, I was tricked by the problem too. I would love to see how a random selection of humans would do on this one… but it just doesn’t feel like a great test to me.
